Heart Failure in Children: The Basics
- In the US, the most common cause of pediatric heart failure is structural congenital heart disease. In children with structurally normal hearts, cardiomyopathy is the most common cause of heart failure. [Hsu et al, 2009]
- Heart failure presents when the metabolic demands of the body exceed cardiac output.
- Clinical Presentation is Diverse & Age related. [Madriago et al, 2010]
- Neonates: Feeding Difficulties and ultimately Failure to Thrive
- Older Children: Fatigue, GI symptoms, and exercise intolerance
- Physical Exam:
- “Pulmonary”: Tachypnea, Respiratory Distress (retractions, grunting), crackles on auscultation
- “Cardiac”: Tachycardia, gallop rhythm
- “GI”: hepatomegaly
